Patent number: 8961433Abstract: The present invention describes a system for controlling a thin flexible thermoplastic catheter. The system includes a plurality of shape memory alloy filaments attached to the distal end of the catheter, each filament having a phase and a temperature; a means for receiving a strain value for at least one of the filaments; a means for determining the phase change that will results in the strain value, whereby the phase change is dependent on the temperature and the temperature is dependent on a voltage; and a means for setting the voltage in each filament thereby resulting in movement of the catheter. In addition, a three-degrees of freedom force sensor measures the magnitude and direction of the force exerted on the tip of the catheter. The catheter can be autonomously guided or it can be interfaced to a haptic device. The catheter can also be fitted with microtools.Type: GrantFiled: January 6, 2011Date of Patent: February 24, 2015Assignee: The University of Western OntarioInventors: Rajnikant V. Patel, Jagadeesan Jayender, Suwas Nikumb

Patent number: 7886801Abstract: An apparatus for stacking a plurality of pieces of material has an assembly region, one or more platens on a first longitudinal side of the assembly region, and, a plurality of press rams on a second longitudinal side of the assembly region opposite the first longitudinal side. The press rams are movable transversely across the assembly region to immobilize or partially immobilize pieces of material in the assembly region permitting accurate and precise alignment of the pieces relative to each other in the assembly region.Type: GrantFiled: November 8, 2006Date of Patent: February 15, 2011Assignee: National Research Council of CanadaInventors: Suwas Nikumb, Craig Dinkel

Patent number: 7853303Abstract: A neurological probe has a plurality of stacked electrode elements, each electrode element having stimulation/lesioning and recording electrodes incorporated with a strip of electrically non-conductive substrate. Such a probe is more compact while having a large number of stimulation/lesioning and recording channels.Type: GrantFiled: November 16, 2006Date of Patent: December 14, 2010Assignee: National Research Council of CanadaInventors: Suwas Nikumb, Craig Dinkel, Mandar Jog

Patent number: 7756588Abstract: The invention provides a multichannel electrode (“MC electrode”) which can perform multiple functions such as recording, stimulating and lesioning simultaneously or sequentially upon a single insertion into a target site. In one aspect, the MC electrode further provides imaging and drug delivery capabilities. The invention also provides interface connectors for connecting the MC electrode to external units such as data acquisition and/or stimulation systems. Although the MC electrode and associated connectors and system(s) provide an optimal way to perform deep brain surgical procedures, the MC electrode and associated connectors and system(s) are useful generally in any technique which relies on recording, activating, and/or inhibiting electrical signals produced by cells.Type: GrantFiled: October 6, 2005Date of Patent: July 13, 2010Assignees: London Health Sciences Center, National Research Council of CanadaInventors: Mandar Jog, Suwas Nikumb

Patent number: 6864190Abstract: Disclosed is a process for fabricating luminescent porous material, the process comprising pre-treating a substrate (e.g. crystalline silicon) with laser radiation (e.g from a Nd:YAG laser) in a predetermined pattern followed by exposing the irradiated substrate to a chemical stain etchant (e.g. HF:HNO3:H2O) to produce a luminescent nanoporous material. Luminescent porous material having a luminescence maximum greater than about 2100 meV may be produced by this method. Such nanoporous materials are useful in optoelectronic and other semiconductor devices.Type: GrantFiled: October 17, 2002Date of Patent: March 8, 2005Assignee: National Research Council of CanadaInventors: Yujie Han, Suwas Nikumb, Ben Li Luan, John Nagata
